Genetic diversity and connectivity within Mytilus spp. in the subarctic and Arctic
Climate changes in the Arctic are predicted to alter distributions of marine species. However, such changes are difficult to quantify because information on present species distribution and the genetic variation within species is lacking or poorly examined. Blue mussels, Mytilus spp. are ecosystem e...

Climate changes in the Arctic are predicted to alter distributions of marine species.
